William Blake might have waxed lyrical on the trickiness of catching the "fearful symmetry" of the tiger, but he didn't reckon on Ang Lee. Having braved The Ice Storm and climbed Brokeback Mountain, the director's latest achieves something many thought impossible: adapting Yann Martel's epic novel Life of Pi, a magic realist fable about God and redemption seen through the eyes of a boy stranded on a raft with only a big cat for company.

Ang's in London on Monday to promote his movie version (he's done a "gently astonishing" job according to our own Tom Shone) and we've got some time to put your questions to him.

So … what do you want to know about Ang's take on the book?

As it's his first foray into 3D, perhaps you'd like to get your claws into that topic? Or maybe there's meat in Ang's casting of a total unknown in the lead role? After Waterworld and Battleship, some would say the adage about never working with children or animals could be extended to include films set on water, yet Ang's gone for all three. Fancy knowing why he let himself in for it?

Bear in mind this is a video interview, so keep your questions short and sweet. There's not too much time for a discussion on whether the book's "an elegant proof of God, and the power of storytelling" (sorry Mr President) but we're open to questions on Ang's impressive back catalogue if you're feline nostalgic.

Sharpen those claws. Leave your mark in the comments below.
